Can traccar block IP address？

I have setup traccart servier in my home server，but in my home network， some device always send message to traccart Port. traccart log
also print the device message. So can we block network ip with traccar server?

Meaby it is your virus scanner scanning the network. What is actually the HEX message in your traccar server log?

Yes, it is HEX message. After decode it to text, it look like the device LAN discover message. it report device type, name, LAN address and so on.
It send from my router and smart camera.

There's no embedded firewall or anything like that. You should use external tools, like your OS firewall or software like fail2ban.

Thanks, Anton!
